9DB233AFILF

Overview

The 9DB233AFILF is a zero delay buffer (ZDB) designed for PCI Express clock distribution, supporting Gen1 through Gen6 standards. It features four differential HCSL output pairs driven by a main clock generator. The device operates in PLL mode from 33MHz to 110MHz and bypass mode from 10MHz to 110MHz. Key electrical parameters include a core supply voltage of 3.3V and typical power consumption of 317mW. It accepts spread spectrum inputs and supports both zero delay buffer and fanout modes, ensuring low jitter performance required for high-speed serial interfaces.

Feature Summary

• Four 0.7V HCSL differential output pairs
• PCIe Gen3 phase jitter < 1ps rms; Gen2 < 3.1ps rms; Gen1 < 86ps peak-to-peak
• Supports Zero Delay Buffer and Fanout modes
• Bandwidth programming available with 33MHz to 110MHz PLL operation

Applications

• PCI Express Gen1–Gen6 clock distribution
• Zero delay buffering for high-speed serial links
• Fanout buffering for system clocks

Procurement Notes

Verify the specific suffix 'AFILF' against official Renesas documentation to confirm package type (SSOP or TSSOP), lead-free status, and environmental compliance. Ensure the ordering code matches the required pin count and moisture sensitivity level before procurement.

Selection Notes

Select this component when driving multiple PCIe endpoints requiring low skew and jitter performance. Verify that the input source is a differential HCSL pair from a compatible main clock generator like the 932S421. Confirm that the operating frequency range of 33MHz to 110MHz aligns with the system design requirements.

Part Context

The 9DB233 belongs to the 9DB series of high-performance clock buffers from Renesas. It is part of a family of devices optimized for PCI Express applications, offering backward compatibility across multiple generations while maintaining strict timing specifications for data integrity.
